The Nets’ 20-62 season is over, but each game they won down the stretch with Jeremy Lin at point guard was a bittersweet reminder of the dozens they lost when he was hurt. Human nature had them thinking about the what-ifs and could-have-beens.

And trying to make sure it doesn’t happen again.

“Yeah, it was difficult,’’ said Lin, who had hamstring woes and missed 46 games. “But I think back to it, and what I remember about the season is March on. All that other stuff is like a blur now, to be honest. I can’t believe I sat and watched 50 games. I don’t really even remember doing much of that. … But the more I think about it, it was really tough at times.”

January and February were forgettable, with the Nets going 1-25 over the two months. The Nets were 7-42 when Lin didn’t start this season, but 13-20 when he did, including 10-12 with him in their optimal lineup after the All-Star break.

“Yeah, there’s a lot of promise there, and Jeremy brings so much to the table,’’ Brook Lopez said. “I know it’s just a small sample size, but the way I like to look at it [is] we grew so much in that small time, the sky’s the limit for us.”

But after each win, human nature took over, the Nets asking the same questions their fans were: What if?

“Oh, they definitely were in my head, because that was what we were talking about as a team,” Lin said. “We’ve talked a lot as a team, especially as we started to see that we could beat some of these other playoff teams. After every one of those games, people would be like, ‘Man, if we had our whole team, if everybody stayed healthy…’ That’s a big ‘if’… but that definitely crossed all of our minds a lot.”

The Nets came into the season feeling safe at the point with Lin and Greivis Vasquez, but Vasquez lasted just 39 minutes before being bought out because of ankle woes. Going into this offseason, the question is: Are any of their young point guards viable backups?

“In terms of the point-guard carousel we went through … I have no idea what’s going to happen,” Spencer Dinwiddie said. “I did enough this season to stick for this season. I believe I’m an elite talent, and I hope they do, too.”

He is just one of the guards the Nets need to evaluate this offseason.

“When we started the season, I thought we had Jeremy and the backup settled,’’ coach Kenny Atkinson said. “Now with Spencer, Archie [Goodwin] and Isaiah [Whitehead], we have to answer, ‘Do we have the solution in-house now?’ I think we do, as the backups have played well. [But] we’ll have to look and see what offseason and next year moves we need to make.”

Could one of them be adding another starting-caliber point and having Lin play some of his minutes off the ball? General manager Sean Marks reportedly went to scout CSKA Moscow’s Milos Teodosic for the second time in a month. So, how would Lin respond?

“I completely trust what they’re doing and everything they laid out, and they completely know all my thoughts on everything. … Regarding specific players, I don’t feel I should comment on that,’’ Lin said. “I know the role they want me to have. They want me to be the guy, they want the ball in my hands.

“I played shooting guard all of college, too. Even with Caris [LeVert], I don’t mind [playing off the ball]. I’m like, ‘Hey, I’m going to play off for a little bit while you go ahead and do your thing.’ At the right times I want to be able to insert that. It’s about the mindset or what they’re thinking about me or their vision for me. I’m more concerned about than if I have to slide off the ball every once in a while.”
